- Dynamic Vapor Sorption (DVS) technique was used to measure the moisture intake of a specific compound at certain humidity level.
- a DVS Intrinsic instrument manufactured by Surface Measurement Systems UK Ltd. (London, United Kingdom) was used to measure DVS. The following measurement procedure was used to determine the water vapor absorption of a specific compound.
- a uniform aqueous solution of a specific, target compound was made at 50% concentration. About 1.2 to 1.6 mg of the prepared aqueous solution was added to DVS instrument at zero tare balance. The temperature was then set at 25 °C, and the measurement was performed at various humidity levels. The first measurement was performed at a humidity of 90% to ensure that the sample absorbs the highest level of water in order to minimize the mass transfer barrier during the evaporation process. The typical humidity measurements were then taken at 50%, 40%, 30%, 20%, 10%, and 0% humidity. The dynamics of water absorption was determined by the weight change per minute. If weight change per minute was less than 0.005% of the sample weight, it was deemed that water absorption had reached the equilibrium point. The equilibrium weight at 0% humidity is the sample weight by itself. Thus, the percentage of equilibrium water absorption at various humidity levels was calculated.
- Corneometer measurements were taken on eight subjects to whose skin the gel samples of Table 2 had been applied. About 30 pi of the gel formulation containing the sample compound was applied once (e.g., in a single application with no additional re-applications) in a circle with diameter of about 3 cm on the inner forearm of each panelist. Moisture levels were measured using a Corneometer® CM 825 (available from CK Industries) prior to and at various time intervals after the sample application at a temperature of 22 °C and relative humidity of 50%, wherein the corneometer values recorded are the difference between the corneometer reading at a given time and the initial corneometer reading at 0 hours, which is set at zero.
- Figure 1 shows the average of the corneometer readings for the eight panelists for each of the gel formulations tested over a period of 24 hours The data show that DGA acetamide was superior to the control formulation over the entire time range tested. DGA acetamide showed humectance performance similar to glycerol over 0-6 hours, and the same as glycerol at 24 hours. This excellent humectance performance is provided without the stickiness, tackiness or other undesirable tactile qualities usually associated with glycerol-based personal care products.
